Area Forecast Discussion National Weather Service San Francisco Bay Area 410 AM PST Sat Dec 7 2019

SYNOPSIS. Showery conditions through the morning, then another frontal band will move across the district bringing heavier showers and a chance of thunderstorms. Lingering showers on Sunday but trending drier by afternoon. Dry weather returns early next week.

DISCUSSION. as of 3:20 AM PST Saturday . Showers continue to move southward through the district although the front has weakened considerably. The complex upper low is still offshore, and another shortwave can be seen on IR satellite imagery approaching the coast. A lot of lightning is being detected with this impulse, and SPC has most of northern California under the general thunderstorm risk with a bullseye of marginal severe risk including the North Bay in the Day 1 outlook. Thus, it looks more likely for thunderstorm development this afternoon, especially across the North Bay. Therefore, another flash flood watch is warranted for the Kincade Fire burn area to account for possible brief downpours with thunderstorms in this passing shortwave. The current watch expires at 4 am.

This impulse is forecast to move through by this evening, although showers will linger into Sunday.

Winds remain gusty over the higher terrain, but are decreasing. The wind advisory will be canceled before 4 am. Winds are forecast to be gusty again as this next impulse moves through later today, but are expected to be below wind advisory criteria.

High pressure to build back in by Monday bringing drier conditions to the area. The midweek weather system still looks very weak with rain chances very slim.

AVIATION. as of 04:10 AM PST Saturday . Scattered light showers will continue through the morning hours. Skies are mainly MVFR this morning and this is expected to continue through the day. The upper low offshore will push more energy through the area this afternoon. Moderate to potentially heavy rain showers and a chance for thunderstorms will arrive this afternoon as another front pushes through. Winds this morning will gust to 25-30 kt with gusts increasing briefly this afternoon to 30-35 kt along the front. Occasional lulls have been observed at the terminals overnight and this will continue through the morning. LLWS will be a concern at the terminals through the afternoon. Winds will subside this evening after the front passes through. Scattered showers will persist this evening and overnight but rainfall should be light. MVFR cigs will persist through the end of the TAF period.

Vicinity of KSFO . MVFR cigs with bases 2000-2500 feet. Light scattered showers will persist early this morning and should decrease briefly. Scattered thunderstorms are possible this afternoon with moderate to briefly heavy rain. Southeast winds have gusted to around 30 kt overnight mixed with periods of lighter winds. Lulls in stronger winds will continue through the morning hours. Gusty winds 30-35 kt will be possible this afternoon with locally higher gusts in thunderstorms. LLWS will be a concern today especially during periods of lighter winds at the terminal.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . Borderline MVFR/VFR this morning with bases 3000-5000 feet. Light rain showers continuing through the day. Gusty south to southeast winds to 20-25 kt at MRY and 30-35 kt in the Salinas Valley. Stronger winds above the surface could cause LLWS at MRY up to 2000 ft. Isolated thunderstorms are now possible into the Monterey Bay terminals this afternoon so VCTS has been added to the TAFs.

MARINE. as of 2:38 AM PST Saturday . A secondary frontal boundary will move through the coastal waters today. Scattered thunderstorms will move into the coastal waters which could produce lightning, gusty winds, and possible waterspouts. Breezy to gusty south to southwest winds will continue through the day today before diminishing this evening. A moderate west swell will continue through Sunday. Steep wind waves will continue through the day today creating hazardous seas.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
